Honestly, I thought Professor Pang was a pretty good lecturer. He was straightforward, and I learned more in 20L than I did in 20B (although I had a pretty bad professor in 20B and I did take 20L after 20B).

The grading scheme was: 18% prelabs, 35% postlabs, 7% "lab technique" (which I can only assume was a freebie depending on your TA), 8% CPRS (theres 2 of them), 10% midterm and 22% final. Therefore, your TA determines about 60% of your grade, so it helps having a nice one who won't take off too much for sig figs or miscalculations. (Side note, I had Dimitri Bikos and I definitely recommend switching to him if you can)

Your CPRS are writing assignments on certain topics graded by people in your class, so if someone decides to be a bitch and mark you off for something, yes that can lower your grade, but its weighted against 2 other peoples' assessment of your CPR, and your own assessment of it based on the program's grading scale. Basically, the closer the average of the 3 scores are to the score you gave yourself, the better your grade will be.

The midterm and final were pretty hard. His study guides are kind of useless, its just questions of every topic he covers. It's definitely not a guideline to the types of questions he puts on the tests. You might as well do them though, considering there's no other way to study for his tests.

For the final, study your post-labs. At least for my class, he put alot of "freebies" in a sense that had to do with stuff we learned from the labs themselves, so actually study your labs, not just the process but everything about it.

Overall, it's a hard class, and you will put a lot of time into it. The post-labs and pre-labs are very tedious. You can't get around not having Pang for 20L, since Pang teaching a lab is more regular than a lunar cycle. However, you can control the TA you get, somewhat. Do whatever it takes to get into a good TA, because that's more than half of your grade. You can even try making up some excuse that you have schedule conflicts unless you go to a certain lab at a certain time. Also, it helps to take the class with someone you know, so the labs will run smoother and you can work on the post-labs at your own discretion.

Before I say anything, PLEASE DON'T MISS THE MIDTERM. This is an 8am class so if you are one of those people that always oversleep....be careful. As stated in the syllabus, you will not be able to make it up for any reason besides serious illness with doctor's note. The midterm is only 10% of your grade, but he has a rule where you have to get 50% in each category to pass the class. In the testing category, the midterm accounts for roughly 31% and the final, 69%. So if you miss the midterm, you must score at least 73% on the final to pass the class. Let me warn you beforehand though, his finals are HARD.

The grades you get on your labs depend solely on your TA. In a sense, the professor doesn't affect your grade much since midterm and final combined are only 32% of your grade. So I wish ya'll good luck on getting an easygoing TA! Get old labs from people if possible; they help A LOT. Lectures are not as important, but make sure you have someone get you notes. Study guides help you get the general concepts, but move on after understanding them and don't spend much time working out the problems. Review your calculations on your lab write ups instead to apply those concepts.

I would recommend taking him because he really cares about you being able to learn the materials. Go to OH if there is anything you don't understand and you will most likely get the help you need.

20L is a hard class, let's get this straight. In order to get good grade, you need to put a lot of work into this class, so expect about 5-6 hours a week to work on the post/pre-labs, and extra 2-3 hours for the writing assignments. Pang also said he wouldn't curve the class, but he gave this extremely hard final that he ended up curving it anyways in the end I believe.
The final had nothing similar to what he gave in the practice one so really, good luck on it. My advice is to go over the slides and understand every single word written on them.
Postlabs and pre-labs, even though they may not be that hard, take some work to understand them thoroughly, which is one thing you should do to prep for the final.
I did all those things and ended up with an A for the class.
Good luck to you all!

P/S: I'm selling all the postlabs/prelabs, course reader as well as all the notes I took in the class( good review for midterms and finals ). Contact me via lynguyen1402@yahoo.com

He gives you study guide and practice questions before exams,but,when you see the test,it's another world, anyway,you still need to do that for preparation.There is a final practice exam which gives 2 bonus points.Do it!The lecture gives a general information guide for the course and he talks fast to cover the material in 50 minutes. Lab work and CPR are lot of work.
